Abstract

Il est décrit une méthode et un appareil servant à effectuer le duplexage par répartition dans le temps (DRT) dans une unité démission et de réception sans fil (WTRU). La méthode en question consiste à recevoir une première configuration de liaison montante ou descendante de DRT prévue pour une cellule de service, recevoir une deuxième configuration de liaison montante ou descendante de DRT prévue pour cette cellule de service, recevoir une indication des directions à utiliser pour les sous-trames ayant des directions se croisant entre les configurations des première et deuxième liaisons montantes ou descendantes de DRT, déterminer le calendrier de la liaison montant et de la demande de répétition automatique hybride de la liaison montante au moyen de la première configuration de liaison montante ou descendante de DRT, déterminer le calendrier de la liaison descendante et de la demande de répétition automatique hybride de la liaison descendante au moyen de la deuxième configuration de liaison montante ou descendante, déterminer une direction de chacune des sous-trames dont les directions se croisent en fonction de lindication obtenue, recevoir la liaison descendante dans une sous-trame dont les directions se croisent si la direction déterminée de cette sous-trame constitue la liaison descendante.
